Description

Technical Field

[0001] The utility model relates to the field of novel tobacco products and aerosol generating devices, and in particular to an aerosol generating device and an aerosol generating system. Background Art

[0002] As health awareness grows, consumers are increasingly demanding tobacco products that reduce tar and harm, while pursuing nicotine satisfaction. The global market's demand for innovative new tobacco products has become extremely urgent. In recent years, new tobacco products designed to reduce the release of harmful ingredients and the risk of smoking have seen explosive growth.

[0003] Against this backdrop, the development of heat-not-burn aerosol-generating devices has become a focus of attention. Whether using internal or external heating technology, the cleanliness of these aerosol-generating devices remains a persistent pain point for users. Currently, during the heating process of aerosol-generating products, condensate and heating residues accumulate inside the aerosol-generating device. If not thoroughly cleaned, these residues will be reheated during the next puff. This not only affects the taste of the newly heated aerosol-generating product but also poses health risks from contamination from repeated heating. Therefore, a thorough solution to the cleanliness issue of aerosol-generating devices is imperative.

[0004] In the prior art, aerosol generating devices are typically configured to be detachable. Specifically, a container located within the aerosol generating device for holding the aerosol generating product can be removed from the upper end of the aerosol generating device for cleaning, and the interior of the aerosol generating device can be cleaned from the upper opening of the aerosol generating device. However, this approach requires the container to be removed in order to clean the container and the interior of the aerosol generating device separately, which is inconvenient. Furthermore, because the container is located within the aerosol generating device, residue accumulated in the container from heating the aerosol generating product may leak, further impacting the reliability of the device and ease of cleaning. Multiple cleaning cycles are required during use, and there may be issues with inadequate cleaning, resulting in inconvenient operation. Utility Model Content

[0005] The utility model provides an aerosol generating device and an aerosol generating system to solve the above technical problems.

[0006] In a first aspect, an embodiment of the present invention discloses an aerosol generating device, comprising:

[0007] A main body, for accommodating a power supply assembly;

[0020] According to another specific embodiment of the present utility model, the area formed by the projection of the second opening on the first projection plane is smaller than the cross-sectional area of the insertion end. The first projection plane is a plane perpendicular to the axial direction of the accommodation chamber. The area formed by the projection of the second opening on the first projection plane accounts for 1 / 3 - 2 / 3 of the cross-sectional area of the insertion end.

[0021] According to another specific embodiment of the present utility model, the shape of the projection of the second opening on the first projection plane is approximately semi-circular. The approximately semi-circular shape is formed by a first arc edge and a second edge. The first arc edge is an arc formed by a part of the circumference, and the second edge is a straight line or a curve. The two ends of the first arc edge are respectively connected to the two ends of the second edge.

[0039] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Although the description of the present utility model will be introduced in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this implementation manner. On the contrary, the purpose of introducing the utility model in conjunction with the implementation manner is to cover other alternatives or modifications that may be extended based on the claims of the present utility model. In order to provide a deep understanding of the present utility model, many specific details will be included in the following description. The present utility model can also be implemented without these details. In addition, in order to avoid confusing or obscuring the key points of the present utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0040] It should be noted that in this specification, similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0041] The terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0042] The term "aerosol-generating article" includes an aerosol-generating substrate, which is a material that can provide volatile components when heated. The aerosol-generating substrate can be solid or liquid. For example, the liquid aerosol-generating substrate can include water, solvents, ethanol, plant extracts, and natural or artificial flavorings. The aerosol-generating substrate can also be a paste material, a porous material pouch including the aerosol-generating substrate, or loose tobacco mixed with a gelling agent or adhesive, which can include common aerosolizing agents such as glycerol. Alternatively, the aerosol-generating substrate can include tobacco-containing materials or non-tobacco materials, or can contain both tobacco-containing materials and non-tobacco materials. Non-tobacco materials can be, for example, fragrances that can be volatilized by heating or without heating, which may or may not contain nicotine. Tobacco-containing materials can include, for example, one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. The aerosol-generating substrate also includes aerosolizing agents such as glycerol or propylene glycol. The aerosol-generating substrate can also include additional added components such as nicotine or flavor extracts. For the solid aerosol-generating substrate, a cartridge or cigarette structure can be formed and accommodated in a smoking device to further form a heated cigarette, which will also include a tobacco matrix part and a filter part.

[0043] To make the purpose, technical solutions, and advantages of the present utility model clearer, the following will further describe the implementation manners of the present utility model in detail with reference to the drawings.

[0044] By carefully studying the prior art, the inventors found that during the use of existing aerosol generating devices, after inhaling the aerosol generating article, it is necessary to frequently clean the condensate and residue generated when heating the aerosol generating article in the aerosol generating device. This operation is inconvenient and there may also be problems with incomplete cleaning. The inventors hope to solve the above problems, reduce the frequency of cleaning the aerosol generating device, ensure thorough cleaning, and even achieve cleaning-free operation.

[0045] In a first aspect, referring to Figure 1 、 Figure 2 and Figure 3 , an embodiment of the present utility model discloses an aerosol generating device 10. Figure 1 A side sectional view showing the aerosol generating device 10 is presented, Figure 2 A front view showing the aerosol generating device 10 is presented, Figure 3 A rear view showing the aerosol generating device 10 is presented. The aerosol generating device 10 includes a receiving component 1 and a main body 2. A power supply component is provided inside the main body 2, and the receiving component 1 is disposed beside the main body 2. A receiving chamber 11 is provided inside the receiving component 1. The receiving chamber 11 is located inside the receiving component 1 and can be used to receive the aerosol generating article 9.

[0046] The receiving chamber 11 penetrates the receiving component 1 in the axial direction y of the receiving component 1, and openings are respectively formed at both ends of the receiving chamber 11, specifically the first opening 12 and the second opening 13. Further, the receiving chamber 11 can be in the form of an obliquely opened hole formed on the receiving component 1 (not shown in the figure). At this time, an angle is formed between the axial direction y2 of the receiving chamber 11 and the axial direction y1 of the aerosol generating device 10, and an angle can also be formed between the axial direction y2 of the receiving chamber 11 and the axial direction y of the receiving component 1. In this embodiment, the receiving chamber 11 can extend along the axial direction y of the receiving component 1 and penetrate the receiving component 1. At this time, the axial direction y2 of the receiving chamber 11 is parallel to the axial direction y1 of the aerosol generating device 10, and the axial direction y2 of the receiving chamber 11 is also parallel to the axial direction y of the receiving component 1.

[0047] The first opening 12 is located at one end of the receiving chamber 11 along the axial direction y. For example, the first opening 12 can be located at the upper end of the receiving chamber 11. The second opening 13 is located at the other end of the receiving chamber 11 along the axial direction y. For example, the second opening 13 can be located at the lower end of the receiving chamber 11. The insertion end 901 of the aerosol generating article 9 can be inserted into the receiving chamber 11 from the first opening 12 and reach the second opening 13 (i.e., the aerosol generating article 9 is inserted in place). In Figure 1 the embodiment shown, the axial direction y2 of the receiving chamber 11 is parallel to the axial direction y1 of the aerosol generating device 10. At this time, the aerosol generating article 9 inserts its insertion end 901 into the receiving chamber 11 along the axial direction y2 from the first opening 12 and reaches the second opening 13 (i.e., the aerosol generating article 9 is inserted in place).

[0048] In each of the above embodiments, during the process of inserting the aerosol-generating article 9, the aerosol-generating article 9 enters from the upper end (i.e., the first opening 12) of the receiving chamber 11. After being inserted in place, the insertion end 901 of the aerosol-generating article 9 can abut against the lower end (i.e., the second opening 13) of the receiving chamber 11. Further, after the aerosol-generating article 9 is inserted, at least a part of the side surface of its insertion end 901 passes through the second opening 13 and is placed outside the second opening 13 (refer to Figure 6 and Figure 7 ), that is, a part of the side surface of the insertion end 901 of the aerosol-generating article 9 will be exposed from the second opening 13 of the receiving chamber 11.

[0049] With the above technical solution, the receiving component 1 of the aerosol-generating device 10 is located beside the main body 2, and the receiving component 1 is in a form that is vertically through. When the aerosol-generating article 9 is inserted into the receiving chamber 11 along the axial direction y2, during the user's suction process, the condensate or residue generated when heating the aerosol-generating article 9 can directly leak out from the second opening 13 at the bottom of the receiving chamber 11, so that the accumulation of condensate or residue at the bottom of the receiving chamber 11 can be reduced or even completely avoided. Since the phenomenon of condensate or residue accumulation is reduced or even disappears, the cleaning requirement for the receiving chamber 11 is correspondingly reduced at this time. The user no longer needs to perform cumbersome cleaning steps and can complete the cleaning in a simple way. Further, since a part of the side surface of the insertion end 901 of the aerosol-generating article 9 is exposed from the second opening 13 of the receiving chamber 11, the condensate or residue generated by heating the aerosol-generating article 9 can even almost all leak out from the bottom of the receiving chamber 11, so that even complete cleaning-free can be achieved. In addition, the receiving component 1 is arranged beside the main body 2, and the receiving chamber 11 in the receiving component 1 is also correspondingly located beside the main body 2, and the second opening 13 at the bottom of the receiving chamber 11 is also located beside the main body 2. Therefore, after all the condensate or residue leaks out from the bottom of the receiving chamber 11, it will not leak into the interior of the main body 2, but only fall out from the outside of the main body 2. In this way, not only can the interior of the main body 2 not need to be cleaned, but also there is no need to worry about the condensate or residue generated by heating the aerosol-generating article 9 leaking into the main body 2 and damaging the main body 2.

[0050] Continue to refer to Figure 1, the body 2 includes a first end 101 and a second end 102 on the axial direction y1 of the aerosol generating device 10. The second end 102 is opposite to the first end 101, and the accommodating member 1 is closer to the first end 101 relative to the second end 102. With such an arrangement, after the aerosol generating article 9 is inserted into the accommodating member 1, one side of the aerosol generating article 9 will not be completely blocked by the body 2, facilitating the user's suction. Further, the aerosol generating device 10 is generally in a "7" shape. In addition, a battery 4 is provided inside the body 2. By arranging the accommodating member 1 closer to the first end 101, when the battery 4 is arranged in the body 2, it is easier to stagger the positions of the battery 4 and the accommodating member 1 in the axial direction y1, which is beneficial to preventing the negative impact on the accommodating member 1 caused by the battery 4 heating up during use. Preferably, a hand-held portion 21 is defined between the second opening 13 of the accommodating chamber 11 of the aerosol generating device 10 and the second end 102 of the body 2, facilitating the user to grip when using the aerosol generating device 10 and improving the user's hand-held experience.

[0051] Further, the opening of the second opening 13 faces the obliquely downward direction z. After the aerosol generating article 9 is inserted in place, a part of the insertion end 901 is exposed from the second opening 13. With such an arrangement, when the aerosol generating article 9 is being suctioned, air can enter from the bottom end of the aerosol generating article 9. In addition, since a part of the insertion end 901 protrudes out of the second opening 13, the liquid or residue generated when the aerosol generating article 9 is heated can directly leak out from the second opening 13 completely, and hardly adheres to the side wall of the accommodating chamber 11 around the second opening 13, which is beneficial to achieving substantially cleaning-free and omitting the cleaning step.

[0052] In the above embodiments, the second opening 13 further includes a structural feature 14 arranged at an angle to the axial direction y2 of the accommodating chamber 11. The structural feature 14 can act on the insertion end 901 of the aerosol generating article 9 to deform the insertion end 901, which can prevent and / or reduce the residue (such as tobacco shreds and tobacco residues) of the aerosolizable substance of the aerosol generating article 9 from falling, and is also beneficial to the accommodating chamber 11 to hold the aerosol generating article 9, preventing the insertion end 901 of the aerosol generating article 9 from protruding excessively from the second opening 13. Exemplarily, the structural feature 14 can include an arc concave surface.

[0053] Continue to refer to Figure 1The second opening 13 further includes a first side 131 and a second side 132. The first side 131 is located on one side of the second opening 13 in the radial direction x. The second side 132 is located on the other side of the second opening 13 in the radial direction x. The second side 132 is farther away from the first opening 12 relative to the first side 131 in the axial direction y2 of the accommodating chamber 11. The connection between the second side 132 and the sidewall 111 of the accommodating chamber 11 is a circular arc concave surface (i.e., structural feature 14). The circular arc concave surface (i.e., structural feature 14) is recessed relative to the interior of the accommodating chamber 11. The circular arc concave surface (i.e., structural feature 14) is used to receive the aerosol production product 9. When the aerosol generating product 9 is inserted into the accommodating chamber 11 and into place, a portion of the insertion end 901 needs to be exposed from the second opening 13. Therefore, after the aerosol generating product 9 is inserted into place, the arc concave surface (i.e., the structural feature 14) will squeeze and deform the insertion end 901 of the aerosol generating product 9. Preferably, the aerosol generating product 9 is squeezed and deformed into a shape that matches the arc concave surface (i.e., the structural feature 14). By squeezing and deforming the aerosol generating product 9, not only can the aerosol generating product 9 be effectively fixed in an appropriate position in the accommodating chamber 11 to prevent the aerosol generating product 9 from sliding or falling off, but it also plays the role of clamping the aerosol generating product 9. During the user's heating and inhalation process, it can also prevent the aerosol generating product 9 from being stuck to the lips, thereby improving the user experience.

[0054] Further, refer to Figure 6 and combined Figure 7 Since the aerosol generating product 9 is squeezed and deformed by the arc concave surface (i.e., structural feature 14), the squeezed and deformed portion of the insertion end 901 of the aerosol generating product 9 (for example, it can be the bottom end of the aerosol generating product 9) helps to increase the air circulation resistance and increase the inhalation resistance. If the inhalation resistance is too small, the air flow will be too fast when the user inhales, and the user may only be able to inhale air and it will be difficult to inhale smoke. In this embodiment, when the aerosol generating product 9 is heated and the user inhales, air directly enters from the bottom of the insertion end 901 of the aerosol generating product 9 that has been squeezed and deformed. During the entire heating and inhalation process, air directly flows from the outside to the inside of the aerosol generating product 9 and then to the oral cavity. There is almost no aerosol retention inside the containing chamber 11, and therefore there is almost no residual condensate and residue anywhere. Furthermore, since the insertion end 901 of the aerosol-generating article 9 is squeezed and deformed, the aerosolizable material (e.g., tobacco) at the insertion end 901 of the aerosol-generating article 9 is also squeezed against each other, thereby preventing residue of the aerosolizable material (e.g., tobacco residue) from falling during inhalation. The above-described technical solution not only improves the draw resistance and puffing experience of the aerosol-generating article 9, but also almost completely prevents condensation and residue from remaining within the container 11, thereby achieving complete cleaning-free operation.

[0055] In addition, by setting the connection between the second side wall 132 and the side wall 111 of the accommodation chamber 11 as an arc concave surface (i.e., the structural feature 14), even if condensate or residue accidentally remains in the accommodation chamber 11, there will be no cleaning dead corners during cleaning, which helps to thoroughly clean the accommodation chamber 11, and the cleaning process is simple and convenient.

[0056] Continue to refer to Figure 6 and combine with Figure 7 , the length H of the insertion end 901 of the aerosol-generating article 9 exposed from the second opening 13 is 1 - 2 mm. Since the insertion end 901 of the aerosol-generating article 9 usually contains an aerosol-generating matrix (such as tobacco materials like shredded tobacco), setting the exposed length H within this range helps to reduce the waste of the aerosol-generating matrix at the insertion end 901 of the aerosol-generating article 9, and can also prevent the smoke drawn in from entering the accommodation chamber 11 due to too short an exposed length, thereby avoiding the formation of contamination in the accommodation chamber 11 by the adhesion of the smoke, which helps to achieve the cleaning-free of the aerosol-generating device 10.

[0057] Set the first projection plane as the plane perpendicular to the axial direction y1. As Figure 4 shown, the shape and size of the first opening 12 on the first projection plane can be seen from the top view of the aerosol-generating device 10. Denote the first opening area formed by the projection of the first opening 12 on the first projection plane as A. As Figure 5 shown, the shape and size of the second opening 13 on the first projection plane can be seen from the bottom view of the aerosol-generating device 10. Denote the second area formed by the projection of the second opening 13 on the first projection plane as B. Denote the area formed by the projection of the aerosol-generating article 9 on the first projection plane as S. Among them, the area S formed by the projection of the aerosol-generating article 9 on the first projection plane is the cross-sectional area of the insertion end 901 of the aerosol-generating article 9 (for example, it can be the cross-sectional area in the radial direction of the aerosol-generating article 9). The area formed by the projection of the second opening 13 on the first projection plane is smaller than the cross-sectional area of the insertion end 901 of the aerosol-generating article 9, that is, the second area B is smaller than the area S formed by the projection of the aerosol-generating article 9 on the first projection plane.

[0058] Since the area formed by the projection of the second opening 13 on the first projection plane is smaller than the cross-sectional area of the insertion end 901 of the aerosol-generating article 9, therefore, even if the accommodation chamber 11 is vertically through, the aerosol-generating article 9 will not fall out from the bottom after being inserted into the accommodation chamber 11, but will be abutted by the second opening 12.

[0059] Furthermore, the size of the first opening 12 can be made to match the shape of the aerosol-generating article 9. For example, when the aerosol-generating article 9 is cylindrical, the first opening 12 can be set to a size that matches the cross-section of the aerosol-generating article 9. In this case, the first opening area A formed by the projection of the first opening on the first projection surface is substantially the same as the area S formed by the projection of the aerosol-generating article 9 on the first projection surface, and the second area B formed by the projection of the second opening 13 on the first projection surface is also correspondingly smaller than the first opening area A.

[0060] In the above embodiment, the second area B occupies 1 / 3 to 2 / 3 of the cross-sectional area S of the insertion end 901 of the aerosol-generating article 9. Within this range, the aerosol-generating article 9 is more likely to remain in the receiving chamber 11 after being fully inserted into the receiving chamber 11, and will not fall out of the bottom of the receiving chamber 11.

[0061] refer to Figure 4 The first opening 12 is projected onto the first projection surface in a circular shape. Furthermore, the first opening 12 can be configured in other shapes, as long as it matches the shape of the inserted aerosol-generating article 9. The size of the first opening 12 is substantially the same as the cross-sectional area of the aerosol-generating article 9. In this way, the first opening 12 can also serve to limit the aerosol-generating article 9, preventing the upper end of the aerosol-generating article 9 from shaking after insertion, thereby reducing the negative impact on the user's puffing experience.

[0062] refer to Figure 5, the shape of the second opening 13 projected onto the first projection plane is semi-circular-like, which is enclosed by a first arc edge 134 and a second edge 133. Among them, the first arc edge 134 is an arc formed by a part of the circumference, the second edge 133 is a straight line or a curve, and the two ends of the first arc edge 134 are respectively connected to the two ends of the second edge 133. Among them, the connection method of the two ends of the first arc edge 134 and the two ends of the second edge 133 can be arc connection, straight line connection, or curve connection. With such a setting, when the aerosol-generating article 9 is cylindrical, the shape of the first arc edge 134 matches the shape of the aerosol-generating article 9, which helps the aerosol-generating article 9 to be fixed in the receiving chamber 11 and fit against the side wall of the receiving chamber 11. Further, the first arc edge 134 can also be set into other shapes, as long as it matches the shape of the bottom end of the inserted aerosol-generating article 9. The second edge 133 can be set as a straight line, a curve, or other shapes, as long as the projected area of the second opening 13 on the first projection plane is smaller than the cross-sectional area of the bottom end of the aerosol-generating article 9. Further, by designing the shape of the second opening 13 projected onto the first projection plane as semi-circular-like, the bottom end of the aerosol-generating article 9 inserted into the receiving chamber 11 will also be correspondingly squeezed and deformed, and the shape of the bottom end of the aerosol-generating article 9 projected onto the first projection plane will also be semi-circular-like accordingly, which can prevent the aerosol-generating article 9 from slipping out of the second opening 13 after being inserted, and can also increase the draw resistance, thereby enhancing the user's sensory experience during suction. In addition, the atomizable substances (such as tobacco) at the insertion end 901 of the aerosol-generating article 9 are squeezed against each other, which can prevent the residue of the atomizable substances (such as tobacco residues) from falling during suction.

[0063] In the above embodiments, the receiving component 1 can be detachably connected (not shown in the figure) or fixedly connected to the main body 2 (that is Figures 1 - 7 the shown aerosol-generating device 10, the aerosol-generating device 10 is integrally formed). Among them, the detachable connection method can be, for example, snap connection, slide rail connection, etc. By setting the receiving component 1 and the main body 2 in a detachable form, it helps to clean and maintain different components separately. In addition, when the receiving component 1 or the main body 2 is damaged, it is also convenient to directly replace the corresponding component.

[0064] Continue to refer to Figure 1, the receiving component 1 further includes a heating element 3. The heating element 3 is used to heat the aerosol-generating article 9 accommodated in the receiving chamber 11 and is arranged around the aerosol-generating article 9. For example, the heating element 3 can be arranged outside the receiving chamber 11, or at least a part of the heating element 3 can constitute at least a part of the receiving chamber 11. Optionally, the heating element 3 includes a heating tube which is sleeved outside the receiving chamber 11 and is used for externally heating the aerosol-generating article 9 inserted into the receiving chamber 11. Among them, any external heating method can be applied to the aerosol-generating device 10, such as resistance heating, electromagnetic heating, infrared heating and other methods.

[0065] The heating element 3 includes a first heating element end 31. The first heating element end 31 is the end of the heating element 3 close to the first opening 12. The distance C1 between the first heating element end 31 and the first opening 12 is 5 - 20 mm. Setting C1 within this range, when the user sucks, the upper end of the heating element 3 that generates heat will not be too close to the first opening 12, nor will it be too close to the user's mouth when the user sucks, which helps to prevent the surface of the housing near the first opening 12 from being overheated, and further helps to prevent the user from being scalded when grasping the aerosol-generating device 10 or sucking the aerosol-generating article 9.

[0066] Exemplarily, when the axial direction y2 of the receiving chamber 11 is parallel to the axial direction of the aerosol-generating device 10, the first heating element end 31 is the end of the heating element 3 close to the first opening 12 in the axial direction y2, and the distance C1 between the first heating element end 31 and the first opening 12 in the axial direction y2 is 5 - 20 mm.

[0067] The heating element 3 further includes a second heating element end 32. The second heating element end 32 is the end of the heating element 3 close to the second opening 13. The distance C2 between the second heating element end 32 and the second opening 13 is 5 - 10 mm. Setting C2 within this range helps to prevent the bottom end of the aerosol-generating article 9 and the housing of the receiving component 1 from overheating during heating, and helps to prevent the user from being scalded.

[0068] Exemplarily, when the axial direction y2 of the receiving chamber 11 is parallel to the axial direction y1 of the aerosol-generating device 10, the second heating element end 32 is the end of the heating element 3 close to the second opening 13 in the axial direction y2, and the distance C2 between the second heating element end 32 and the second opening 13 in the axial direction y2 is 5 - 10 mm.

[0069] Furthermore, a heat-insulating material can be arranged on the outer periphery of the heating element 3, which can further prevent the heat generated when the heating element 3 is heated from dissipating to the outside, helps to play a role in heat preservation and insulation, avoids the outer housing from being overheated, and helps to ensure the high efficiency and safety of the heating process. The heat-insulating material can be, for example, aerogel, graphene, etc.

[0070] Continue to refer to Figure 1 ,the power supply component in the body 2 includes a battery 4, and the battery 4 is arranged axially misaligned with the accommodating component 1 along the axial direction y1 (that is, the battery 4 and the accommodating component 1 may partially overlap or not overlap in the axial direction y1). During the use of the aerosol generating device 10, when the battery 4 works, it will generate heat, and the heating element 3 in the accommodating component 1 will also generate heat. With such an arrangement, the accommodating component 1 and the battery 4 are not completely adjacent, and the accommodating component 1 and the battery 4 are misaligned with each other, so as to avoid the distance between the battery 4 and the heating element 3 being too close and the heat being too concentrated, which helps to ensure the safety in use during the heating process. Preferably, the battery 4 and the accommodating component 1 are arranged at intervals along the axial direction y1, that is, the battery 4 and the accommodating component 1 do not overlap in the axial direction y1, which can further increase the distance between the battery 4 and the heating element 3, further prevent the heat from being too concentrated during use, and help to further improve the safety in use during heating.

[0071] Furthermore, the power supply component further includes a main circuit board 5, and the main circuit board 5 is located on the side of the body 2 away from the accommodating component 1. During the use of the main circuit board 5, since it is powered on and there is current, it may also generate heat. Arranging the main circuit board 5 on the side away from the accommodating component 1, that is, away from the heating element 3, helps to avoid the heat being too concentrated between the heating element 3 and the main circuit board 5 and improve the safety of using the aerosol generating device 10.

[0072] Furthermore, there is a sufficiently large distance between the main circuit board 5 and the accommodating component 1 to arrange heat insulation materials, and there is a sufficiently large distance between the main circuit board 5 and the battery 4 to arrange heat insulation materials, which helps to further play the role of heat insulation between different components, prevent the mutual influence of the heat generated when different components work, and helps to ensure that the operating temperatures of the battery 4 and the main circuit board 5 are within a reasonable range (for example, the reasonable ranges of the operating temperatures of the battery 4 and the main circuit board 5 are both -5°C to 65°C), and improve the safety of using the entire device. The heat insulation materials can be, for example, aerogel, graphene, etc.

[0073] Continue to refer to Figure 1 ,the aerosol generating device 10 further includes a charging circuit board 6 and a charging interface 7. The charging circuit board 6 and the charging interface 7 are located below the battery 4 and are used to charge the battery 4, and the distance between the charging circuit board 6 and the main circuit board 5 is relatively far, and the mutual interference and influence between the main circuit board 5 and the charging circuit board 6 are small, which helps to ensure the overall reliability of the aerosol generating device 10.

[0074] The aerosol generating device 10 further includes an indicator light 8. The indicator light 8 can be used to indicate the start of heating, the end of preheating, the end of the heating process of the entire aerosol generating article 9, the start of charging, the end of charging, etc. Further, the indicator light 8 can also be used as a button to control the aerosol generating device 10 to heat the aerosol generating article 9. In addition, the indicator light 8 can also be used to indicate whether the aerosol generating device 10 has a fault, or to indicate the battery power status of the aerosol generating device 10. Exemplarily, when the aerosol generating device 10 has a fault, the indicator light 8 can flash a yellow light. The indicator light 8 can also indicate a fault by changing the light color or by changing the flashing frequency of the light. When the aerosol generating device 10 is in a state where the aerosol generating article 9 is not heated, pressing the indicator light 8, the indicator light 8 can indicate the battery power status.

[0075] In the aerosol generating device 10 of the present utility model, by arranging the accommodating component 1 beside the body 2 and setting the accommodating chamber 11 in the accommodating component 1 to be vertically through-shaped, during the use process by the user, the condensate or residue generated by heating the aerosol generating article 9 can directly leak out from the second opening 12 at the bottom of the accommodating chamber 11. Therefore, after the user finishes sucking, the accumulation amount of the condensate or residue in the accommodating chamber 11 is less, or even almost none, so that the user does not need to perform a cumbersome cleaning process, saving the user's time and energy and facilitating the user's use. Further, after the aerosol generating article 9 is inserted from the first opening 12 and reaches the second opening 13, a part of the insertion end 901 of the aerosol generating article 9 protrudes from the second opening 13, which further helps the condensate and residue generated during the heating process of the aerosol generating article 9 to almost completely leak out of the accommodating chamber 11, further helping to reduce the cleaning requirement for the aerosol generating device 10, and even achieving complete cleaning-free. In addition, by providing the arc concave surface 14, not only can the bottom end of the aerosol generating article 9 be squeezed to increase the draw resistance, but it is also convenient for cleaning without cleaning dead corners. The aerosol generating device 10 of the present utility model can reduce internal dirt, condensate and bacterial growth, be more hygienic, and can also improve the sucking taste. There is no residual residue, condensate and peculiar smell in the accommodating chamber 11, and a more pure sucking experience can be provided. In addition, arranging the accommodating component 1 beside the body 2 can also avoid possible damage to the inside of the aerosol generating device 10 during the cleaning process and extend the service life. Further, by arranging the accommodating component 11 and the battery 4 at intervals in the axial direction y1 and arranging the main circuit board 5 on the side far from the accommodating component 1, it is also possible to avoid excessive heat concentration generated when different components work, which helps to ensure the use safety. By setting heat insulation materials at corresponding positions, the heat insulation and heat preservation effect can be further improved.

[0076] In a second aspect, an embodiment of the present utility model also discloses an aerosol generating system, which includes the aerosol generating device 10 and the aerosol generating article 9 in any of the foregoing embodiments.

[0077] With the above technical solution, in the aerosol generating system of the present utility model, the aerosol generating device 10 disposes the accommodating component 1 beside the main body 2 and forms the accommodating component 1 in a through form. After the aerosol generating article 9 is inserted into the accommodating chamber 11 of the accommodating component 1, a part of the side surface of the insertion end 901 of the aerosol generating article 9 can be exposed from the second opening 13, which can reduce the accumulation of residues generated during the heating of the article in the device. The residues can directly leak out from the bottom of the accommodating component 1, and even almost no residues will be left in the accommodating component 1, and they will not leak into the main body 2 of the aerosol generating device 10. It can also reduce the cleaning of the aerosol generating device 10, and even achieve complete cleaning-free.

Those skilled in the art can make various changes in form and detail, including making several simple deductions or substitutions, without departing from the spirit and scope of the present utility model.
